Re: [hammond_zone] Novice on board

Hi Macinkilt,

Welcome to the group. As to your question about the F's on your M3, the notes on the Hammond are built up from a mixture of frequencies generated by spinning toothed wheels (hence "tonewheel" generator), the exact mix of frequencies depends on what drawbars or pre-sets you have selected. The wheels are driven by gears from a synchronous motor so the overall tuning of the organ is locked to the AC mains frequency. It is difficult to imagine a scenario where all the wheels responsible for F notes would go off tune by the same amount as there are no more than two wheels sharing a common shaft and set of gears. It may be that you are missing some frequencies and the Bb you are hearing is the result of the fundamental frequency missing on some notes, and only a harmonic being heard. You can check out all the tonewheels individually by pulling out one drawbar at a time and playing one key at a time all the way up the keyboard. Make a note of any keys that don't play and on which drawbar and I will be able to help you further. Note that the higher pitched drawbars do not go all the way up the keyboard and that the black drawbars do not play unison pitch, i.e.. on the first black drawbar a "C" key will actually play "G" with a corresponding shift for all other keys.

A special tool is required to remove the dingle arm. This is because it's buried under the lower udatulator plate. This tool, which was Hammon part # B2-02T564, consisted of a stratifed pentagrid plate modulator that would maintain the algebraic relationship of the generator coil flux to the magnetic field set up by the nofer trunnions. With this relationship maintained, the dingle arm can be withdrawn through the fennel orifice with out fear of excessive skor motion. Raul ----- Original Message -----

Re: [hammond_zone] G-100 question
Richard B. Ahlvin
my G-100 has a "Trompette 8" in the pedal division, and I've playedanother one that had a "Bombarde 16" instead. What's the story with that? Are all G-100's not the same? I would guess that since it is technicaly rather simple to create a stop sound (requires a handful of resistors), that Hammond could have easily customized organs to a certain extent for special customer specifications.

Re: [hammond_zone] stops and couplers versus drawbars
OOPS, sorry about that empty post... I hit "send now" rather than "X" when I
wanted to start from scratch. For an alternative to "take the highest number" check out "Hammond Organ Additive Synthesis" by Paul Schnellbecker He explains why his system is superior. He also gives some examples of "re-programming" the presets - an improved version of the stock presets, and a set for liturgical use (which is what I put on both my A-105 and the A-100 at my church). Another page to look at is - a list of 221 pipe organ stops translated to drawbars. I have a copy of this document in MS Word format at . I've tried a few of these at random, I've generally been happy with the results. Doug |

In order to create the desired effect, one must first understand how pipe organs work, and once that is done, then naturally, adding the numbers will seem 'not the right thing to do'. When you draw stops on a traditional organ, you're not necessarily making the ensemble louder. I posted the list of stops and their drawbar equivalents for two reasons. First, it's nice to see how all the different stops can be produced using the drawbars, and also to help people out when it comes to adding a certain stop to the ensemble. While stops cannot be drawn on the Hammond organ one after the other to produce a 'combination' of registers, the effect of a combination can be achieved, but in a different manner. The largest number for each harmonic becomes the proper intensity in the final ensemble. >> |

all these charts of translated pipe organ stops to hammond drawbars sound pretty good, as long as you want to hear them still alone. But as you might know, in classical music you have to mix stops like Fifteenth 2....00 0002 223, Flageolet 2....00 0004 112, Nazard 2 2/3....00 0040 030 or Tierce 1 3/5....00 0000 500 with fond stops almost beginning from the 8'- or even 16'-ranks. So on a hammond you can't simply add the numbers, like you do with the stops of a pipe organ, but you must listen carefully to the hole sound of all mixed stops and then try to reproduce it with your hammond and the slow choral speed of your leslie(s). Do it with the help of your ears, not by lists! Nevertheless you won't get the real pipe-organ sound. Perhaps people are impressed first, but if they would have a direct comparison at the same location with a real pipe-organ - no computer-clone - they could hear the differences very soon. But why copying pipe-organs with hammonds, these trials have failed always since the first attempts of Laurens Hammond and others? I like playing Frescobaldi, Bach, Mendelssohn, Franck, Reger, Karg-Elert a.o. on my XB-3 with a 32-tone-AGO-midi-pedal made by Doepfer/Manger with additional stops from a XB-2 placed on the XB-3 like a third manual. Mostly I use 00888-basic and add a little bit of 4' and 2' to the great, 2 2/3', 1 3/5' and 1 1/3' to the swell and some others to the solo if needed. I always thinking of using the higher overtones like spices in the kitchen... My dream would be a good Hammond-Concert-Modell E, builded from 1937 till 1942 with 32-note pedalboard, chorus generator and two expression pedals... Last year, I had the oportunity to hear a RT-3, which was for sale with PR-40 and Leslie 760, but although it had only little technical defects, the sound didn't impress me too much. So I made my decision for the XB-3 and a modified Leslie 723. Sincerely, Hans-Bernd Message: 24 |
Tonewheel description
marc saint-f¨¦lix
Hi all,
I'm looking for a technical decription of the tonewheels operating principles. I need something which develops two orientations : mechanics (wheels, clutches, shafts,...) and electrics (mostly electromagnetic fields involved in TWG). I already checked a couple sites like prokeys, they have nice pictures btw, but I'd like more "scientific" descriptions. I need this for my electro-mechanical class. They want us to introduce an electro-mechanical device, I didn't have to think for too long to find a topic!! By the way, the prokeys site is at . Please tell me this guy is excessively pessimistic and tell me I will play my B3 for the next 30 years with no problem!! If you read this article you will probably all look at your tonewheel generator as a rusty old piece of trash waiting for death but already burried in a moth-eaten coffin.... Thanks, Marc. |

When the 200mfd. cap failed, (it almost certainly has been destroyed by the reverse voltage) it would have changed the bias on the output valves (tubes) as you shut the power off quickly it is probable that no harm will have been done to the valves. The purpose of this cap. is to decouple (remove any signal voltage from) the 150 ohm 10 watt cathode bias resistor for the 6550 valves. Source for 200 mfd. 50 volt cap? Radio shack? Do they still do components? Ask your local TV and radio repair shop, if they haven't got the part in stock, they could probably order one from their suppliers. Nearest equivalent in modern component range would be 220 mfd 63 volt, this will do just fine. I've just looked in the "Maplin" catalogue (UK equivalent of Radio Shack) 220 mfd 63 volt is ???0.15, cheap enough to change anyway. How long to "soak test" when you've finished repair? How long is a piece of string? Within reason the longer the better, most problems are likely to show within an hour, remember all the original components have had many years to "burn in" so it's not as if you're testing a whole load of new parts. If it's not smoking after a couple of hours it'll likely go another 30-40 years. Might be a good idea to consider changing the rest of the electrolytic capacitors at some time though.

need help with leslie 147 amp
Hi fellow hammond zoners,
I just got a leslie 145 that apears to be in really clean shape inside and out, there is literaly no dust in this thing at all. It came out of a church along w/ a matching M3. The pastor had just transfered to that church and found the organ and leslie in non functional condition, he sent an email to a friend of his in another state ( this friend had asked him to look for old hammonds at the church)and asked him to come and haul away the rig for free. Well he did, and then sold it to me for a song. Before I bought it he inspected the amp but never fired it up. he found a 200 mfd. 50V electrolytic capacitor rolling around under- neath the amp chassis. I looked at the schematic and parts list and determined that this was C9 and it had broken of. So I soldered it back on, and started to bring it up to 120V on my variac (1V per minute) Well I got to 90V and started to hear a hissing sound coming out from underneath the chassis, then I heard a sound that bad lighting ballasts make (a 60Hz hum) but it sounded like it was coming out of the power transformer. I shut of the Variac right away, Then I touched all of the transformers, only the power transformer was hot, I also touched the C9 it also was very hot, I forgot to touch the can capacitor.I am very thankfull there was no smoke. After all of this I looked at the schematic again and realized that I had soldered the cap with the positive lead to ground instead of the negative to ground like it should be. Needless to say I feel really stupid because I thought that I checked that. My first question is did I cause severe damage to the amp by doing this? I only had it up to 90V Also can I remove the C9 and solder it on properly, or has that been damaged by this? What is the function of this capacitor? Where can I find a good replacment 200 mfd. 50V electrolytic? What is the best duration of time to variac the 147 amp once I've replaced the capacitor? Any help with this matter would be greatly welcome, I can't wait to get this baby fired up. And on a lighter note I oiled up the motors and hooked them up to my homemade switching system, then rigged the speakers W/ the crossover to a 15 watt fender guitar amp... It sounded great and loud to boot. Thanks alot, Tim aka '65 bassman |

Hammond spinet, can't remember enough detail to identify the model. In those days the BBC still had that quaint old fashioned idea that records should reproduce a live performance, not the other way round. Acts appearing on T of the P had to perform live in the TV studio, miming to the record was not allowed!!!
